Inventor: UEHARA IZUSHI
IPC: G06F15/16
Filed: 1989-06-02
Granted: 1993-05-11
Abstract: Abstract of the Disclosure In an intercommunication network for use in transmitting a transmission request from a first processor to a second processor, the first processor sends a first processor number preassigned thereto through a system bus to the second processor which holds a communicable processor number corresponding to the first processor number and which detects whether or not the first processor number indicates the first processor by monitoring correspondence between the first processor number and the communicable processor number.  A destination processor number assigned to the second processor may not be transmitted from the first processor because identification is made in the second processor.  Thus, no destination processor number is administrated in the first processor.  The first and the second processors may belong to a lower rank and an upper rank, respectively, and may be an input/output processor and an execution processor unit, respectively.

Abstract: A multizone test device for the determination of analyte from a liquid test medium upon contact with the liquid test medium and a labeled reagent comprising a chemical group having a detectable chemical property. The test device preferably comprises multilayers including a reagent layer incorporated with an immobilized reagent and a detection layer incorporated with an immobilized form of an interactive detection reagent for the labeled reagent. The immobilized reagent in the reagent layer and the labeled reagent comprise specific binding partners which will bind to each other dependent upon the amount of analyte present. Labeled reagent which does not become bound to the immobilized reagent in the reagent layer migrates into the detection layer and interacts with the immobilized interactive detection reagent therein which results in the localized generation of a detectable reaction product which preferably is also immobilized in the detection zone. As a result, reverse migration of the labeled reagent, and preferably the detectable reaction product from the detection layer is prevented and the detectable chemical property provided by the label of the labeled reagent is localized in the detection layer for the precise measurement thereof and correlation to the amount of analyte in the test medium.

Abstract: A method for enzyme immunoassay for a ligand suspected to be present in a liquid sample includes signal amplification by use of at least two enzymes and a blocked modulator for one of the enzymes. Ligand present in the liquid binds to an antiligand and an enzyme-labeled tracer. The resulting bound fraction is separated and the enzyme in the tracer removes the blocking group from the blocked modulator. The modulator activates or inhibits a second enzyme which catalyzes the conversion of a substrate to a product. The presence or absence of the ligand in the liquid is indicated by a signal, such as a color change or a rate of color change, associated with the product. The invention includes a new class of enzyme inhibitors and blocked inhibitors and a kit of materials useful for performing the method of the invention.

In order to produce an image of the dry line range on wire this is illuminated by means of a large, diffusely illuminating surface (20) of even luminosity. The material on moving wire (10) is imaged by an optoelectric camera (40) on a detector whereby the pulp surface preceding the dry line and being specularly reflecting is found homogeneous and bright while the web surface following it and being diffusely reflecting is found homogeneous but matter and darker. The electric image signal delivered by the detector is conducted to a computer (50) in which the dry line is identified as the borderline of said surfaces of different brightness. Its deviations from target values are determined for both the average value and different values in cross direction and the corresponding actuators are adjusted in order to control the paper web on the basis of deviations observed for its different parts or for its whole breadth. Dry line and values of quantities and deviations characterizing it are also presented on a display terminal, whereby said controls can alternatively be effected by a human observer.
